To quote: I start developing PS3MFW Builder 0.2.1 a few mouths ago, and since then it's just laying around my computer. It's fully working, only one function should rewritten.



  • Choose language.
  • Select Temp folder.
  • Select PS3_KEYS folder.
  • Save/Default all the settings, including selected/unselected tasks, original/modified firmware paths, theme and so on.
  • For developers: you can restart PS3MFW Builder by pressing .


I added the option to translate PS3MFW Builder to any language, including RTL, unique symbols and so on.. Thanks to eussNL for creating most of the translations.

You can also easily create your own translation, all the text it stored in an .xml file.


  • Added the option to select multiple files using "files" option type.
  • Added the option to select directory using "directory" option type.

Developers: The only thing should be rewritten is the "save_settings" function. The best way is to add a function in xml.tcl which will replace the text in specific node.

Finally, from zecoxao: I have here (linked above) with me a version of mfw builder based of cfwprpht's mfw builder v3. it works, on the aspect that the auto gen tool properly generates both AC1D and Rogero 4.30 CFWs and on the aspect that the other tasks also work, but not only for 4.30. they also work for 4.46 unfortunately i can't test the pups because i don't have a flasher. if any of you wishes to give it a shot, then please take your chance.

PS: I removed that sha1 thing, it was driving me crazy
PPS: Some lv2 related tasks don't work on 4.46 but work on 4.30 with the auto gen task

Just a warning. those might not actually be the correct "fake private keys"

Here (linked above) are the patched loaders in decrypted format for 4.46. just followed Rancido's instructions:

From Rancid-o: You have to extract manually the loaders from the LV0, decrypt them, patch the ecdsa check, encrypt the ldrs and reinsert them in LV0. Patch finded in Rebug 4.41:

i've created my custom 4.10 kiosk/shop firmware by using the original 4.10 firmware and swapped each file in dev_flash/vsh/module manually, found a better method of replacing the files by creating a desktop shortcut and just drag and drop with windows, got a red screen error after the first test install but then swapped /vsh/etc/ index.dat and version.txt and it works fine. anyone know the unlock code for 4.10 kiosk/shop firmware? thanks.

A CFW?, if you use MFW builder won't be able to install it pass FW 3.55. To see what I mean, use MFW builder with an original retail 4.10 pup and make it extract and re-pack the dev_flash without changing anything inside the dev_flash. Then when you try to install it you get the error "data is corrupted".

Normally retail FW will not install kiosk FWs under normal circumstances. As far as I know, there is a flag inside the pup which identifies the update as retail/kiosk/debug. As this knowledge was used to patch 3.55 cfws so they would install on 3.55 kiosk FWs. I have done experimenting and found the flag offsets insides each variation of the 4.10 update.

Update Flag Offsets:

I am 90% certain that these are the flag offsets, as they match the ones found inside extracted .pups. But changing them for me doesn't seem to do anything for me on my un-hacked OFW4.10 PS3. But we've had differing results with our PS3s before haven't we. Perhaps they might work for you.

its working now, thanks for your help. CFW soon!

do shop/kiosk firmwares noramlly show up on ps3 retail when you try and install them on retail? i'm sure i tried one before and it normally says (shop) firmware, anyway i'm trying to patch shop 4.10 but it always says no update data found, the only other option i have is replace each file in dev_flash 1 by 1 which is a freaking nightmre. help! thanks

Error running script: error deleting "C:/Temp/PS3MFW-MFW/update_files/dev_flash\dev_flash\vsh": file already exists

Change the "\" to "/" Maybe that's your problem?

that is a windows explorer error, if you replace files with this task. i recommend you to use another filebrowser and do not browse the folder where you replace the file, or you can close the browser after replace
